For the next two weeks people passing through Berlin's Kurfürstendamm shopping boulevard will notice a giant campaign from Mini, telling them "It's Personal." The BMW offshoot is hitting Germany's capital with an interactive Photo Box, a booth that captures the faces of Mini fans and blasts them onto a massive video screen along with each participant's favorite Mini model for a chance to win their preferred car.

Contestants have four colors and four models choose from, including the Mini Hatch, Convertible, Clubman and Countryman. Fans around the world can join in the fun through the Facebook app, where you can snap a picture with your webcam wearing a pair of virtual headphones in your favorite Mini color.

Participating is as simple as that. The lucky winner will take home their favorite Mini with customized side mirrors that match their favorite color. To get in on the action, check out Mini's live stream of the giant video screen consuming the side of a building on Kurfürstendamm, take your photo and upload to win. The contest ends 29 May 2011.
